Title: Mapping and ablation catheter system

Abstract: A recording and ablation catheter method and system for creating linearlesions in an atrial or other chamber of a heart is disclosed whichincludes an array of readily controlled electroded arcuate distal workingcatheter shapes that are easily deployed to contact the inner wall surfaceof the right atrial cardiac chamber in a manner that enables easyrecording and mapping of impulses and thereafter facilitates sustainedcontact so that linear lesions can be produced from an array of mappingand ablation electrode devices serially spaced along the working cathetershape.
